“The magnitude and speed of the decline is unprecedented among birds distributed over such a large area, with the exception of the Passenger Pigeon, which went extinct in 1914 due to industrial-scale hunting”, said Dr Johannes Kamp from the University of Münster, the lead author of the paper.

Although there is a lack of hard data about the population of Yellow-breasted Bunting, there is much anecdotal evidence of its decline, as outlined in the paper, and there can be no doubt that the contraction in its range and the reduction in numbers recorded at communal wintering sites are very real.

And it was in September 2013 that we found a bird trapper at Nanpu, on the Hebei coast, using a caged Yellow-breasted Bunting as a lure alongside some mist-nets.

The trapper was surprisingly cooperative as we dismantled the nets and freed the trapped birds.A distressed-looking male Yellow-breasted Bunting, now officially an endangered species after years of persecution.

So it has been with some surprise and delight that, this autumn, there have been record numbers of Yellow-breasted Buntings seen in Beijing. Definitely something to celebrate!

Here are a few recent counts:

44 on 26 August 2015 at Miyun Reservoir (Paul Holt and Terry Townshend). Exactly double the previous Beijing record count!

Although data are sparse, the records we have from Birdtalker (the Chinese bird record database) show no change in the species’ status in Beijing in last 10 years. The important caveat here is that there has been much more observer coverage of good habitat this year, especially in late August (the peak period for autumn migration of this species).

Whatever the reason, we are very happy to see good numbers of this most beautiful of buntings.

Here is a photo from this autumn in Beijing and two short videos – the first of adult male singing on the breeding grounds (in Mongolia) and the second of autumn birds in Beijing.
